— Zero-valent aluminum (Al 0) is an excellent electron donor with extremely low redox potential (E 0 (Al 3+ /Al 0) = − 1.667 V) that could directly activate the green oxidant O 2, producing reactive oxygen radicals to effectively degrade pollutants in the Al 0 /O 2 system. However, the surface of Al 0 is covered with a dense oxide film and easily re …
